TIRE-CASING.

Specification of Letters Patent.

Application filed July 12, 1913. Serial NQ. 778,681.

T0 all-whom it may concern:

Be it known that I, WILLIs'G. MORRIS, a citizen of the United States, residing at State f Nebraska, haveinvented certain new and useful Improvements in Tire-Cas ings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art vto which it appertains to. make and use the same.

My invention relates to new and useful improvements in protecting casings for vehicle tires.

The object of my invention is to provide a sectional, non-perforable casing adapted to cover the tread of a resilient vehicle tire, which will not interfere with the function of the tire.

With this object in view, the invention consists in the improved construction, arrangement and combination of the parts of a device of the character specied, which will be hereinafter fully described, and afterward specically claimed.

In order that the construction and operation thereof may be readily comprehended, I will now proceed to fully describe my invention in connection with the accompanying drawings, which illustratean approved embodiment thereof, and in which drawings, Figure l represents a View in elevation showing a wheel and the approved form of' my casing in place over the tire thereof". Fig. 2 represents a detail sectional view through the telescoping ends of two adja cent sections of the casing employed by me. Fig. 3 represents a perspective view 'of one end of one of the casing sections. Fig. l represents a detail view showing a portion of a casing section with outer elevations, and Fig. 5 represents a sectional view on 'the plane-indicated by the broken line 5-5 of Fig. 2.

Like reference characters indicate the same parts wherever they appear in a plul rality of the figures oi the drawings.v

Referring specifically to the drawings, l5

indicates the rim of a wheel, which may be of any desired construction, and shaped to carry a pneumatic tire 6. In order that the pneumatic tire 6 may be protected. from injury and Wear, I secure my improved form of casing over the tread thereof. The protecting casing is formed of a plurality of tion. When adjacent sections arel assembled upon a tire, the ends thereof are adapted to Patented June 15, 1915.,

telescope, as shown in. Fig. 2, so 'that the tread and inner surfaces of said sections will be in alinement. vVhe'n the sections are disposed around the tread of a tire, the ends of the sections are telescoped, as indicated in Fig. 2, and when litted snugly on the in Hated tire, are held in such relation and in close engagement with the tread of the tire by means of the coil springs 10which have their opposite ends secured to the ends of adjacent sections, as clearly shown in Fig. l, forming a tire protecting casing having a smooth outward surface, without projecting ribs or other non-skid devices. It will beobserved that the-sections of the casing are U-shaped in cross section to fit over the tire and that the tongues 9 and chambers 8 are of similar shape.v By this construction, it will be seen that the sections of the protecting casing will be closely held-in engage ment with the tread of the tire upon which they are placed.

When'the wheel is in operation and a load is supported by the tire, the adjacent ends nosuxmngltheir normal positions when the wheel has turned suiiciently to carry said ends away from the ground.

In Fig. 4,1 have shown a section of a tread casing, the 'tread portion of which is provided with a plurality of outwardly extending elevations 12 which are adapted' to engage in the 'surface of the ground, over which the wheel is traveling, and prevent slipping or skidding of the same. Any other form of non-slipping projections may be formed integrally with or secured upon the sections oi' the casing. l/Vhile I have specifically described the enact construction and arrangement of the component parts of my invention,I it will a circle, e chamber formed in one end of in testimony whereof I tion what I Gleim end desire '$0 secure 'by edges of he iolngue engegiw #he l' Letters Patent of the Unltec States 1s.` oi he chamber to prevenuJ jeter tire Acasmg comprising; a plurehey of 'ment of Mie `ongue during' sections, U-shaped inv cross section, and movement, and resilient mean@ L curved longitudinally to form e poruon4 of t e sections adjacent the comers if each section having slde we11s,-a tongue neme to this specification formed in the opposite end having Siae JWo subsci'ibng WilnesfsesQ edges parallel with, but ofses from the side l WHJLIS G. edges or the section, said tongue adapted to Witnesses: snugly seat in the chambelfI of e neighboring JOHN RUSSELL,
